The Ethics-Committee of the Faculty of Theology is responsible for ethical review of research-projects, which are conducted within the Faculty of Theology (Theology and Study of Religions). It's members have been elected by the Faculty-Assembly and are not bound by directives in their practice.
A vote by the Ethics-Committee can be necessary when applying for research-funding (e.g. by the SNF) or in the context of publications research-work – especially when conducting research with human participants (e.g. conducting interviews).
Further information on the necessity of an ethics-vote can be found here.
